Improvement in faucets

JOHN FAHRNEY, OF BOONSBOROUGH, MARYLAND, ASSIGNOR TO HIMSELF AND SAMUEL FAHRNEY, OF SAME PLACE.

IMPROVEMENT IN FAUCETS.

Specification forming part of Letters Patent No. 57,818. (lated September 4, 1866; alltdated August 23, 1866.

To all whom t may concern:

Be it known that I, JOHN FAHRNEY, of near Boonsborough, in the county of Washington, in the State of Maryland, have invented a new and Improved Faucet for Drawing and Measuring Molasses, Sirup, Oil, Sto. 5 and I do hereby declare that the following is a i'ull and exact description thereof', reference being had to the accompanying drawings, and to the let.- ters of. reference marked thereon.

Similar letters in the several figures refer to corresponding parts.

Figure l is a longitudinal vertical section of the faucet, with a perpendicular view of screws ffand binding-screws gg. Fig. 2 is a view ot' the lower surface ot' the piston, showing the crescentic openings a.v a through it. Fig. 3 is a view ot' the under surface ot' the neck E, with a portion of its wall removed, as shown at M. p

This faucet consists of a hollow cylinder, A, terminating at one end in a neck, B, upon which is cut a screw-thread. rIhe other end is closed by a cap, C, with a hole through its center, as shown at D. To said cap is appended a hollow neck, E, in which plays a cutoft' piston, F, with a hole through its center,

in which slides the piston-rofl Gr.

H is a valve, closing the entrance of neck B. I is a piston, with two crescentic openings, a a, through it and excavated on its inner surface, as shown by dotted lines b b. C is a hole through the piston, in which the piston-rod slides as far as the shoulder d. J is a circular plate, fastened on the end ot' the piston-rod, and large enough to close the openings a a in the piston I. K is a nut, firmly fastened on the piston-rod, with a projection, e. L is a plate, sunk in a groove transversely through the upper wall ot' the neck E. A portion ot' the lower wall of neck E is removed or cut out, as shown at M. N is the handle, by which the faucet is operated. f f are gage-screws.

Operation: To use this faucet the neck B is screwedV horizontally into the tap-hole of the Vessel containing the substance to bev drawn. N ow, grasp the handle N and revolve the piston-rod until the projection e of nut K clears the plate L. Then draw upon the handle until the piston I stops against the gage-screws fj'. While this is being done the circular plate J closes or is drawn tightly against the piston I, and closes its crescentic openings c a air-tight, the valve H opens, and the liquid tlows through the neck B and iills the cylinder A. N ext, push back the handle as t'ar as ffit will go. While this is being done the pis- `ton-rod G slides through the piston I as far as the shoulder d, valve H closes, and the circular plate J, being separated from the piston I, the liquid ilows through the openings a a and tills the cylinder A, behind the piston l. Now, draw upon the handle again until the piston I stops against the gage-screws ff. While this is being done the liquid forces the cut-ott' piston F back against the plate L, and the liquid flows out through the opening M, made by the removal ot' a portion of the lower wall of neck D. Repeat these operations until the desired quantity is drawn, and push back the handle and lock the projection e behind the plate L as it was in the beginning.

The set of the gage-screws limits the stroke ofthe piston Land thereby the quantity drawn at a single operation.

The size I pret'ert'or this faucet isjust large enough `to be regulated to draw halt' a pint at a single operation.

/Vhat I claim as my invention, and desire to secure by Letters .Patent ot' the United States, is

l. The cylinder A, with valve H, in combination with piston I, with its openings ct a, its rod G, sliding through and turning in its center, as shown at c d, and the circular plate J, attached to end of the piston-rod, as and for the purposesdescribed.

2. In combination therewith, the cut-ott' piston F, neck E, with its lower Wall removed, as shown at M, as and for the purposes described.

3. The nut H, with its projection e, plate L, and gage-screws fj', as and for the purposes described.
